Abstract—ETFE (Ethylene Tetra Fluoro Ethylene) is a light weight foil with architectural beauty which is commonly used as building material. However to improve the poor heat insulation, deposition of multiple layers of low-emissive coating is necessary. During winter large amount of heat can be trapped since the property of low-e coating includes reduction of radiative part of heat loss with the increase in infrared reflection and decrease in infrared emission. Thus the reflective property stops emission of radiant heat outside, keeping the produced radiant heat inside. The simulation of 2 layer ETFE pillows is performed using Dymola Simulation software with and without low-e coating. The simulation showed a significant reduction in U value from 2.6 to 1.7.
